No.17812 Tafoid Administrator Jul 5, 2020, 00:11	Possible regression revision found testing daily builds - January 4, 2020 https://github.com/mamedev/mame/commit/4c40152837f0625242be10264fa0fa47d8bc1c72 I'm unsure if this happens for other games as well, only tested this one reported.

No.20107 Robbbert Senior Tester Apr 28, 2022, 12:47	Tested reverting the suspected revision, makes no difference. Currently the game loads up to "COMPLETE" but then reboots, creating an endless cycle. The game is marked as MNW, so should we just close this?

When I tried to load the game and doing the steps above, it now hangs on an error screen with Japanese message that I'm not sure what it says. If anyone knows how to bypass that error screen, like to know how to get pass it.
